Reservoir 

8 520L0519 • Rev FN • July 2009 




The pump receives fluid directly from the reservoir through the inlet line. A screen in the 

inlet line protects the pump from large contaminants. The pump outlet feeds a PVG-32 

multi-section, load sensing, directional control valve. The PVG valve directs pump flow to 

the cylinder and gear motor. A heat exchanger cools the fluid returning from the valve. A 

filter cleans the fluid before it returns to the reservoir. 

Flow in the circuit determines the speed of the actuators. The position of the PVG valve 

determines the flow demand. A hydraulic pressure signal (LS signal) communicates 

demand to the pump control. The pump control monitors the pressure differential 

between pump outlet and the LS signal, and regulates servo pressure to control the 

swashplate angle. Swashplate angle determines pump flow. 

Actuator load determines system pressure. The pump control monitors system pressure 

and will decrease the swashplate angle to reduce flow if system pressure reaches the 

PC setting. A system relief valve in the PVG valve acts as a back-up to control system 

pressure.

operation 

The PC control maintains constant system pressure in the hydraulic circuit by varying 

the output flow of the pump. Used with a closed center control valve, the pump remains 

in high pressure standby mode at the PC setting with zero flow until the function is 

actuated. This condition is often called a dead head condition.

angle. The pump continues to increase flow until system pressure reaches the PC setting. 

If system pressure exceeds the PC setting, the PC control reduces the swashplate angle to 

maintain system pressure by reducing flow. The PC control continues to monitor system 

pressure and changes swashplate angle to match the output flow with the work function 

pressure requirements. 

If the demand for flow exceeds the capacity of the pump, the PC control directs the 

pump to maximum displacement. In this condition, actual system pressure depends on 

the actuator load. 

Each section includes control schematic diagrams, setting ranges, and response / 

recovery times for each control available. Response is the time (in milliseconds) for the 

pump to reach zero displacement when commanded by the control. Recovery is the 

time (in milliseconds) for the pump to reach full displacement when commanded by the 

control. Actual times can vary depending on application conditions. 

Pressure compensated system characteristics 

• Constant pressure and variable flow 

• High pressure standby mode when flow is not needed 

• System flow adjusts to meet system requirements 

• Single pump can provide flow to multiple work functions 

• Quick response to system flow and pressure requirements

Closed center circuit with remote PC 

P101 966 

The remote PC control uses a pilot line connected to an external hydraulic valve. The 

external valve changes pressure in the pilot line, causing the PC control to operate at 

a lower pressure. When the pilot line is vented to reservoir, the pump maintains a low 

standby pressure of 15 to 20 bar [215 to 300 psi]. When pilot flow is blocked, the pump 

maintains pressure at the PC setting. An on-off solenoid valve can be used in the pilot 

line to create a low-pressure standby mode. A proportional solenoid valve, coupled with 

a microprocessor control, can produce an infinite range of operating pressures. 






Size the external valve and plumbing for a pilot flow of 3.8 l/min [1 US gal/min]. For 

additional system protection, install a relief valve in the pump outlet line.

operation 

The LS control matches system requirements for both pressure and flow in the circuit 

regardless of the working pressure. Used with a closed center control valve, the pump 

remains in low-pressure standby mode with zero flow until the valve is opened. The LS 

setting determines standby pressure.

Load sensing circuit 

P101 967 

Most load sensing systems use parallel, closed center, control valves with special porting that 

allows the highest work function pressure (LS signal) to feed back to the LS control. margin 

pressure is the difference between system pressure and the LS signal pressure. The LS 

control monitors margin pressure to read system demand. A drop in margin pressure means 

the system needs more flow. A rise in margin pressure tells the LS control to decrease flow. 

LS control with bleed orifice 

The load sense signal line requires a bleed orifice to prevent high-pressure lockup of the 

pump control. Most load-sensing control valves include this orifice. An optional internal 

bleed orifice is available, if needed. 

Integral PC function 

The LS control also performs as a PC control, decreasing pump flow when system 

pressure reaches the PC setting. The pressure compensating function has priority over 

the load sensing function. 






Load sensing system characteristics 

• Variable pressure and flow 

• Low pressure standby mode when flow is not needed 

• System flow adjusted to meet system requirements 

• Single pump can supply flow and regulate pressure for multiple circuits

• Priority steering 

• Load independent flow control for boom lift, tilt, and rotation

The electrical on/off pressure 

compensated control allows the pump 

to operate as a PC type control under 

normal operating conditions. A solenoid 

valve overrides the PC control allowing 

the pump to operate in a low-pressure 

standby mode. This function provides 

reduced horsepower and torque loss in 

certain situations. It may be particularly 

useful to reduce loads on a system 

during engine start. 

ED schematic (normally closed) 

S When closed, the solenoid valve prevents 

L1 

P106 044 

flow across the LS spool gain orifice, 

defeating the LS spool. The pump then functions as a PC control pump. When open, 

the solenoid valve allows flow across the LS spool gain orifice to reservoir. This flow 

generates a pressure differential across the LS spool that shifts the spool and de-strokes 

the pump. The pump then operates in a low-pressure standby condition. The solenoid 

valve is available in a normally closed or normally open configuration. 

ED is the nomenclature for a normally closed on/off control for the L and K frame pumps. 

Other frame sizes and configurations have different order code designations.

fluids 

Ratings and performance data for Series 45 products are based on operating with 

premium hydraulic fluids containing oxidation, rust, and foam inhibitors. These 

include premium turbine oils, API CD engine oils per SAE J183, M2C33F or G automatic 

transmission fluids (ATF), Dexron II (ATF) meeting Allison C-3 or Caterpillar T0-2 

requirements, and certain specialty agricultural tractor fluids. For more information on 

hydraulic fluid selection, see Sauer-Danfoss publications 520L0463 Hydraulic Fluids and 

Lubricants, Technical Information, and 520L0465 Experience with Biodegradable Hydraulic 

Fluids, Technical Information.

Pressure ratings 

The specification tables in each section give maximum and continuous pressure ratings 

for each displacement. Not all displacements within a given frame operate under the 

same pressure limits. Definitions of the operating pressure limits appear below. 

system pressure is the differential pressure between the outlet and inlet ports. It is the 

dominant operating variable affecting hydraulic unit life. High system pressure, which 

results from high load, reduces expected life. System pressure must remain at or below 

rated pressure during normal operation to achieve expected life. 

Continuous working pressure is the average, regularly occurring operating pressure. 

Operating at or below this pressure should yield satisfactory product life. For all 

applications, the load should move below this pressure. 

maximum (peak) working pressure is the highest intermittent pressure allowed. 

Maximum machine load should never exceed this pressure. 

speed ratings 

The specification tables in each section give minimum, maximum, and rated speeds for 

each displacement. Not all displacements within a given frame operate under the same 

speed limits. Definitions of these speed limits appear below. 

Rated speed is the maximum recommended operating speed at full displacement and 

1 bar abs. [0 in Hg vac] inlet pressure. Operating at or below this speed should yield 

satisfactory product life. 

maximum speed is the highest recommended operating speed at full power 

conditions. Operating at or beyond maximum speed requires positive inlet pressure 

and/or a reduction of pump outlet flow. Refer to Inlet pressure vs. speed charts for each 

displacement. 

minimum speed is the lowest operating speed allowed. Operating below this speed will 

not yield satisfactory performance. 

Duty cycle and pump life 

Knowing the operating conditions of your application is the best way to ensure proper 

pump selection. With accurate duty cycle information, your Sauer-Danfoss representative 

can assist in calculating expected pump life. 

speed, flow, and inlet pressure 

Inlet pressure vs. speed charts in each 

section show the relationship between 

speed, flow, and inlet pressure for each 

displacement. Use these charts to ensure 

your application operates within the 

prescribed range. 

The charts define the area of inlet 

pressures and speeds allowed for a 

given displacement. Operating at lower 

displacements allows greater speed or 

lower inlet pressure.

DesiGn PaRameteRs installation 

Series 45 pumps may be installed in any position. To optimize inlet conditions, we 

recommend installing the pump at an elevation below the minimum reservoir fluid 

level. Design inlet plumbing to maintain inlet pressure within prescribed limits (see Inlet 

pressure limits, page 13) 

Fill the pump housing and inlet line with clean fluid during installation. Connect the case 

drain line to the uppermost drain port (L1 or L2) to keep the housing full during operation. 

To allow unrestricted flow to the reservoir, use a dedicated drain line. Connect it below 

the minimum reservoir fluid level and as far away from the reservoir outlet as possible. 

Use plumbing adequate to maintain case pressure within prescribed limits (see Case 

pressure limits, page 13). 

filtration 

To prevent damage to the pump, including premature wear, fluid entering the pump 

inlet must be free of contaminants. Series 45 pumps require system filtration capable of 

maintaining fluid cleanliness at ISO 4406-1999 class 22/18/13 or better. 

Sauer-Danfoss does not recommend suction line filtration. Suction line filtration can 

cause high inlet vacuum, which limits pump operating speed. Instead we recommend 

a 125 µm (150 mesh) screen in the reservoir covering the pump inlet. This protects the 

pump from coarse particle ingestion. 

Return line filtration is the preferred method for open circuit systems. Consider these 

factors when selecting a system filter: 

• Cleanliness specifications 

• Contaminant ingression rates 

• Flow capacity 

• Desired maintenance interval 

Typically, a filter with a beta ratio of β 10 = 10 is adequate. However, because each system 

is unique, only a thorough testing and evaluation program can fully validate the 

filtration system. For more information, see Sauer-Danfoss publication 520L0467 Design 

Guidelines for Hydraulic Fluid Cleanliness. 

Reservoir 

The reservoir provides clean fluid, dissipates heat, and removes entrained air from the 

hydraulic fluid. It allows for fluid volume changes associated with fluid expansion and 

cylinder differential volumes. Minimum reservoir capacity depends on the volume 

needed to perform these functions. Typically, a capacity of one to three times the pump 

flow (per minute) is satisfactory. 

Locate the reservoir outlet (suction line) near the bottom, allowing clearance for settling 

foreign particles. Place the reservoir inlet (return lines) below the lowest expected fluid 

level, as far away from the outlet as possible.

shaft loads 

Series 45 pumps have tapered roller bearings capable of accepting external radial and 

thrust loads. The external radial shaft load limits are a function of the load position, 

orientation, and the operating conditions of the pump. 

The maximum allowable radial load (R e) is based on the maximum external moment (M e) 

and the distance (L) from the mounting flange to the load. Compute radial loads using 

the formula below. Tables in each section give maximum external moment (M e) and 

thrust load (T in , T out) limits for each pump frame size and displacement.

Bearing life 

All shaft loads affect bearing life. In applications where external shaft loads can not 

be avoided, maximize bearing life by orientating the load between the 150° and 210° 

positions, as shown. We recommend tapered input shafts or clamp-type couplings for 

applications with radial shaft loads. Tables in each section give B 10 bearing life for each 

pump frame size and displacement.

mounting flange loads 

Adding auxiliary pumps and/or subjecting pumps to high shock loads may overload the 

pump mounting flange. Tables in each section give allowable continuous and shock load 

moments for each frame size. Applications with loads outside allowable limits require 

additional pump support. 

• shock load moment (M S) is the result of an instantaneous jolt to the system. 

• Continuous load moments (M c) are generated by the typical vibratory movement 

of the application. 

Estimating overhung load moments 

Use the equations below to estimate the overhung load moments for multiple pump 

mounting. See installation drawings in each section to find the distance from the 

mounting flange to the center of gravity for each frame size. Refer to the technical 

specifications in each section to find pump weight.

auxiliary mounting pads 

Auxiliary mounting pads are available for all radial ported Series 45 pumps. Since the 

auxiliary pad operates under case pressure, use an O-ring to seal the auxiliary pump 

mounting flange to the pad. Oil from the main pump case lubricates the drive coupling. 

• All mounting pads meet SAE J744 Specifications. 

• The combination of auxiliary shaft torque and main pump torque must not 

exceed the maximum pump input shaft rating. Tables in each section give input 

shaft torque ratings for each frame size. 

• Applications subject to severe vibratory or shock loading may require additional 

support to prevent mounting flange damage. Tables in each section give allowable 

continuous and shock load moments for each frame size. 

• The drawing and table below give mating pump dimensions for each size mount. 

Refer to installation drawings in each section for auxiliary mounting pad dimensions.

input shaft torque ratings 

Input shaft tables in each section give maximum torque ratings for available input shafts. 

Ensure that your application respects these limits. 

maximum torque ratings are based on shaft strength. Do not exceed them. 

Coupling arrangements that are not oil-flooded provide a reduced torque rating. Contact 

your Sauer-Danfoss representative for proper torque ratings if your application involves 

non oil-flooded couplings. 

Sauer-Danfoss recommends mating splines adhere to ANSI B92.1-Class 5. Sauer-Danfoss 

external splines are modified class 5 fillet root side fit. The external major diameter and 

circular tooth thickness dimensions are reduced to ensure a good clearance fit with the 

mating spline. Tables in each section give full spline dimensions and data.

understanding and minimizing system noise 

Tables in each section give sound levels for each frame size and displacement. Sound 

level data are collected at various operating speeds and pressures in a semi-anechoic 

chamber. Many factors contribute to the overall noise level of any application. Here is 

some information to help understand the nature of noise in fluid power systems, and 

some suggestions to help minimize it. 

Noise is transmitted in fluid power systems in two ways: as fluid borne noise, and 

structure borne noise. 

fluid-borne noise (pressure ripple or pulsation) is created as pumping elements 

discharge oil into the pump outlet. It is affected by the compressibility of the oil, and 

the pump’s ability to transition pumping elements from high to low pressure. Pulsations 

travel through the hydraulic lines at the speed of sound (about 1400 m/s [4600 ft/sec] 

in oil) until there is a change (such as an elbow) in the line. Thus, amplitude varies with 

overall line length and position. 

structure-borne noise is transmitted wherever the pump casing connects to the rest 

of the system. The way system components respond to excitation depends on their size, 

form, material, and mounting. 

System lines and pump mounting can amplify pump noise. Follow these suggestions to 

help minimize noise in your application: 

• Use flexible hoses. 

• Limit system line length. 

• If possible, optimize system line position to minimize noise. 

• If you must use steel plumbing, clamp the lines. 

• If you add additional support, use rubber mounts. 

• Test for resonants in the operating range, if possible avoid them.

Frames L and K 

DesiGn Series 45 Frame L and K pumps have a single servo piston design with a cradletype 

swashplate set in polymer-coated journal bearings. A bias spring and internal 

forces increase swashplate angle. The servo piston decreases swashplate angle. Nine 

reciprocating pistons displace fluid from the pump inlet to the pump outlet as the 

cylinder block rotates on the pump input shaft. The block spring holds the piston 

slippers to the swashplate via the slipper retainer. The cylinder block rides on a bimetal 

valve plate optimized for high volumetric efficiency and low noise. Tapered roller 

bearings support the input shaft and a viton lip-seal protects against shaft leaks. 

An adjustable one spool (PC only, not shown) or two spool (LS and remote PC) control 

senses system pressure and load pressure (LS controls). The control ports system 

pressure to the servo piston to control pump output flow.

Frame J 

DesiGn Series 45 Frame J pumps have a single servo piston design with a cradle-type swashplate 

set in polymer-coated journal bearings. A bias spring and internal forces increase 

swashplate angle. The servo piston decreases swashplate angle. Nine reciprocating 

pistons displace fluid from the pump inlet to the pump outlet as the cylinder block 

rotates on the pump input shaft. The block spring holds the piston slippers to the 

swashplate via the slipper retainer. The cylinder block rides on a bi-metal valve plate 

optimized for high volumetric efficiency and low noise. Tapered roller bearings support 

the input shaft and a viton lip-seal protects against shaft leaks. 

An adjustable one spool (PC only, not shown) or two spool (LS and PC) control senses 

system pressure and load pressure (LS controls). The control ports system pressure to the 

servo piston to control pump output flow.

Frame F 

DesiGn Series 45 Frame F pumps have a dual servo piston design with a cradle-type swashplate 

set in polymer-coated journal bearings. The bias piston increases swashplate angle. The 

servo piston decreases swashplate angle. At equal pressure, the larger diameter servo 

piston overpowers the bias piston. Nine reciprocating pistons displace fluid from the 

pump inlet to the pump outlet as the cylinder block rotates on the pump input shaft. 

The block spring holds the piston slippers to the swashplate via the slipper retainer. The 

cylinder block rides on a bi-metal valve plate optimized for high volumetric efficiency 

and low noise. Tapered roller bearings support the input shaft and a viton lip-seal 

protects against shaft leaks. 

An adjustable one spool (PC only, not shown) or two spool (LS) control senses system 

pressure and load pressure (LS controls). The control ports system pressure to the servo 

piston to control pump output flow.

Frame E 

DesiGn Series 45 Frame E pumps have a dual servo piston design with a cradle-type swashplate 

set in polymer-coated journal bearings. The bias piston increases swashplate angle. The 

displacement piston decreases swashplate angle. At equal pressure, the larger diameter 

displacement piston overpowers the bias piston. Nine reciprocating pistons displace 

fluid from the pump inlet to the pump outlet as the cylinder block rotates on the pump 

input shaft. The block spring holds the piston slippers to the swashplate via the slipper 

retainer. The cylinder block rides on a bi-metal valve plate optimized for high volumetric 

efficiency and low noise. Tapered roller bearings support the input shaft and a viton lipseal 

protects against shaft leaks. 

An adjustable one spool (PC only, not shown) or two spool (LS) control senses system 

pressure and load pressure (LS controls). The control ports system pressure to the 

displacement piston to control pump output flow.
